PROBLEM TO BE SOLVED: To provide a control apparatus capable of raising injection accuracy by determining injection characteristics while raising degrees of freedom of selection of an injector in the case of driving the injector in a partial lift area and a full lift area.SOLUTION: An ECU 28 which is a control apparatus is provided with an injection control part 281 and a characteristic determination part 282. The injection control part 281 executes characteristic control in which, from a state in which a fuel injection amount equal to or less than the total injection amount of fuel is allocated to fuel injection from a port injector 18 and the remaining fuel injection amount of the total injection amount is allocated to fuel injection from an in-cylinder injector 19, the fuel injection amount from the port injector 18 is reduced and the fuel injection amount from the in-cylinder injector 19 is increased according to the reduced fuel injection amount. The characteristic determination part 282 executes characteristic determination for determining injection characteristics of the in-cylinder injector 19 based on an air fuel ratio to be detected according to the characteristic control.SELECTED DRAWING: Figure 2 |
